Embodiments of the invention provide a method and device for optimum design of directional sign layout information layout. The method comprises the following steps of: dividing a directional sign layout into four function areas according to directional sign layout information layout features; obtaining visual cognition understanding accuracies of different directional information combination formsof each function area, and selecting the directional information combination form, having the highest visual cognition understanding accuracy, of each function area to form an initial optimum layoutof a directional sign; obtaining visual cognition times corresponding to different information amounts of the initial optimum layout through visual cognition experiments of drivers, and obtaining a visual cognition model of the directional sign according to the visual cognition times; and obtaining a target optimum layout of the directional sign layout according to the visual cognition model. According to the method and device, the ability of understanding and visually cognizing the directional signs by drivers is comprehensively considered, so that understanding features of the drivers can besatisfied, visual cognition characteristics of the drivers are met, and the correctness of optimum layout of directional sign layout information is improved.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of transportation, and in particular to a method and device for optimizing layout information layout of a guide sign. Background technique [0002] As an important part of road infrastructure, road signs can provide road information for drivers during driving, and play an important role in the driver's destination search and driving route confirmation, which directly affects the driver's travel efficiency and travel safely. Although "Road Traffic Signs and Markings" (GB 5768-2009, hereinafter referred to as "National Standard") has been promulgated and implemented in 2009, the national standard regulations are relatively broad, and the situation in each region varies greatly, and only some cities have formulated detailed implementation rules. As a result, the guide signs in different regions show great differences in layout and information volume, which increases the driver's drivi...
